High reliability: Member switches in a stack work in redundancy mode. Link redundancy can also be implemented between member switches through inter-device link aggregation.
High scalability: You can increase ports, bandwidth, and processing capacity of a stack by simply adding member switches to the stack. Member switches can join or leave the stack without affecting other member switches. New switches automatically synchronize the configuration file and system software version with the master switch.
Simplified configuration and management: You can log in to a stack from any member switch to manage and configure all the member switches in the stack. In addition, complicated Layer 2 ring protection protocols or Layer 3 protection switching protocols are not required after switches set up a stack, making the network configuration much simpler.
Configuration Procedure:
Three switches form a stack.
Power off the switches, install one stack card on each switch, and power on the switches.
Configure stack IDs and stack priorities for member switches to facilitate management.
[Switch1] stack slot 0 priority 200 //master
[Switch2] stack slot 0 renumber 1 //standby
[Switch3] stack slot 0 renumber 2 //slave
3. Power off Switch, Connect stack ports and power on the switches.
When connecting stack cables, connect STACK1 port of one switch to STACK2 port of another switch
